Leah Messeris not only newly engaged, but she’s also expecting many more good things with her fiance, Jeremy Calvert: he proposed on Christmas Day AND the Teen Mom 2 star is pregnant with her third child! Read on for details on his holiday proposal, as well as her own good news.

Jeremy Calvert shared the news that he’s is expecting a child with Leah Messer, who had twins Ali and Aleeah with former husband Corey Simms.

“Yes, Leah is having my baby!” Jeremy says. “I was at work when Leah called to tell me. She’d gotten blood work done and it came back positive. At first I was kind of surprised — but I was happy.”

Though the divorce between Leah and Corey was finalized this past June, Jeremy didn’t wait long: he proposed to Leah on Christmas Day. “I bought an ornament for the tree that said ‘Engaged’ with both our names on it and the date. And when I saw Leah looking at it, that’s when I gave her the ring.” He gave her a 1.5 carat princess-cut diamond; the couple found it while window shopping and Jeremy returned with a friend to secretly buy it later on.

“Baby Ali is the one who said yes first,” Jeremy says. He shares that he and Corey are on good terms.

How does Jeremy feel about expecting a child so soon after popping the question? Apparently, quite confident! “Nothing ever gets Leah down,” he says. “She stands strong for the kids. And I know that no one is better to have as your kids’ mother than Leah.”
